Re: Homebrew GPSDO
A really cheap way to check the 10MHz would be one of the GPS modules using the u-blox NEO-7M (well under £10).
These can be programmed to give an output frequency up to 10MHz in 1Hz steps.
The catch is that there will be considerable jitter on output but averaged over a period of a few seconds or more, using a counter or by eye using an oscilloscope, sub Hz accuracy at 10MHz is easily attainable.
Programming can be done via 'u-center' software on a PC (via a USB-TTL serial converter) or using an arduino or similar.
